To all whom N; Hwy (Jill/6. 72

Be it'known that I, Holmes VVYYMAN, a citizen of the United States, residing at -viorcestcr, in the county of Worcester and State of l /lassachusetts, have invented certain new and useful Improvements in Automatic Weft-Re plcnishing Looms, of which th" following is a specification.

My invention relates to looms, and particu larly to automatic Weft-replenishing looms of the class shown and described in United States Letters Patent No. 600,053, of March 1, 1898, in which a magazine or reservoir of the well known Northrop type (shown and described in United States Letters Patent No. 529,940, of November 27, '1894lis provided at one end of the loom, containing bobbins or filling-car riors of different colors, which are automatieally supplied to'theshuttles on the breaking of the filling or the substantial exhaustion of filling in the running shuttle in the usual and well-known way, and change or shifting shut-- tle-boxcs'are provided at the other end of the loom and connections are provided intermediate the shiftingshuttle-boxes and the magathe magazine for the supply of filling of the desired color to the running shuttle, according to the movement of the shifting shuttleboxes In the class of looms referred to lilling-deteetor mechanism is ordinarily employed on the shifting-shuttle end of the loom to detect the substantial exhaustion of fiiling in the running shuttle, and there are connections intermediate said filling-detector mechanism and the transferrer mechanism of the fillingsupply mechanism on the opposite end of the loom to cause the operation of the transfer-rel mechanism to supply new filling to the running sln'ttlo in the well-known way.

The object of my invention is to improve upon the construction of some of the parts of a l. -m of the class referred to and more particmarly to improve upon the construction of the magazine or filling-supply mechanism which carries the bobbins or filling-carriers and the operation thereof. as will be hereinal'ler fully described. 4 s

in my improvements the iillingsupply mechanism has preferably two compartments,

for a series ofbobbins, and each series is prefagainst said stop.

transferrer to transfer a bobbin directly from one of said compartments into the running scuttle when the lay is in its forward position. in case of two compartments 'for the bobbins one compartment will preferably be upon one side of the transferrer and the other compartment upon the opposite side, and the com part ments will h vs a rocking or reciprocating movement. An abutting surface or stop is provided at the lower end of the compartments to retain thebo'bbins in each compartment and with the lowest bobbin in each compartment in such a position that it will be either in a position under the transferrer to be transferred into the running shuttle or will be automatically moved into ppsition by the rocking movement of the cdriipartments, ac cording to the movement of the shifting shuttle-boxes, and when the active shuttle in one compartment of the shuttle-boxes has its filling practically exha usted and the transfer of new filling is about to take place.

in my improvements as shown in the draw ings-and hereinafter described, a filling-supply magazine of the Northrop type is used, which is centrally mounted above the transferrcr and has a rocking" or reciprocating movement instead of a'rotary movement, as is customary, and the two compartments for the bobbins are concentric with each other, forming two circular guideways within the periphery of the two end plates or disks of the magazine. One guideway is for the heads and the other guideway for the tips of the bobbins. The gaideways of the compartments for the bobbins are preferably made open at their upper part for the free placing of the heads ,nd the tips of the bobbins in the compartments, and the bobbins drop down by gra ity within the compartments on opposite sides of the pivotal support of the magazine to the lower ends of the compartments or guideways. A single division is preferably employed between theg'nideways for the heads of the bobbins at the lower ends of the guideways, which forms a terminal or stop for the bobbins in each compartment, and the lowest bobbin in each compartment at its head bears The lower ends of the gnideways for the heads and the tips of the bobbins in each compartment'are made open to allow of the passage of the lowest bobbin in either compartment when said bobbin is in];

position under the transferrer, and suitable spring devices are nrovicled i yieldingly hold the tips of their/o lowest bobbins, one in each compsrhneni, end :1 spring device 18 also provided for holding she head of the bob,

I have shown in the drawings, Figs. 1 and 2, s filling-detector mechanism located at the shifting-shuttle-box end of the loom and having' in this instance two feelers adapted to enter the shiittleboxes'anci detect the substani-ial exhaustion of filling therein and in case of the substantial exhaustion of filling in either shuttle-box to opernhe through intermediate connections the trensf-errer at the opposite or filling-supply end of the loom to supply new filling to the single shuttle in; that end of the loom. The filling-detector mechanism referred to may be of any ordinsry and well-known constrnoiion and operaizion; hnhli have shown in the drawings o iilling-detecbor mechanism of the-type shown is United States Letters Patent No. 665,845, to which reference is hereby mode. in said nnienlv the feelers and the feeler-frenie have veriicsi reciprocating movement with the shifting shubtlobo'xes as they are raised and iowercrl. i have shown in the drawings the lieeieni'rsme carrying the feelers es hnving'al pivot-cl iYlOlTiOD. This pivotal motion of the feeler-frnine carrying the ie'elers i do not claim my invention; but the some is made Elie snlojecn-inatter of another application for Letters Patent by me, the serial number of which. is 259570,

I will briefly describe the filling-detector mechanism shown in the drawings.

ihe upper end of said connector 23 is pivotnlly connected to the inner end of the feeler-fraine 24c, which in shis instance is shown as pivot silysunporsed st 25 in in uprighl; stand 26. (Seel ig. Ll The feelers 27., in this instance ,i he which: wires 28 end 29,, lending The lower end of-e connector ssis connecped with the vertically-moving box-rod 10, and

Lil

to the opposite poles of any suitable source of eiectric energy. Each bobbin 9 has a metal" lie band thereon, which when exposed by the substantial exhaustion of filling on the bob bin attracts the end of a feelcr 2.7 and draws it out of its support, as fully described'in said patent, leaving an opening at the rear of the feeler for the entrance of the upper end of a detector-arm 30, having a hub "pivotally mounted on a pin 31". wardly-extending arin 352- from the hub 30 carries a pin 32 thereon, which is pivotally connected with a rod (see Fig. 2,) which extends transversely across the loom and is connectedwith mechanism at the opposite or filling-supply end of the loom; (Shown in 'Figs. 2, 7, 8, and 9, as will be hereinafter described.)

1n conneetionwith' the filling-feelermechanism above described i have shown .in the drawings mechanism shown and described in said Patent No. 655,845 for positively oper* .ating the detector-arm 3O intermittentlyat regular intervals to move the same and the mechanism connectedtherewith to their nor-' mal position after a 'feeler has indicated fora change of filling, as above described. Said mechanism comprises a lever '35, centrally pivoted on a stud 36 and having its inner end in the path of and engaged by a cam 37, fast on the bottom shaft 14 and held in engagement therewith by a spring (See Fig. 1 'lheopposite end of the lever has pivotally attached thereto the lower end, oi: a' connector. 39. The upper end. of the connector 39 is pivotally connected with one arm of an anglelever 40, pivotally mounted. The other arm of said angle-lever t0 carries a pin 41, on which is pivotally mounted theinner end "of a longitndinally-moving rod 512. 'lhe'outer end of said rod 42 is supported and has a reciprocating motion in a stand 43. (See Fig. 2.)

At predetermined intervals, according to the shape of the cam 37 -pre'ferabIy every other pick, through the lever 35, connector 39Tan'd angle-lever 40, the rod &2 is moved outwardly to engage the detector-arm 30 below its pivotal support and move the upper end of said arm inwardly ag inst the action of the spring 34 to return ad, same and the mechanism connected therewith to their normal position after the feeler 27 has indicated for a change of filling, as stated above.

Fast on the bottom shaft 14- is a cam 44.,-

which engages and operates the lower end of the cam-lever 45, pivoted at e6. The upper end of the lever 45 extends in the path of and is adapted to engage the. inner hooked end of the filling-fork 47,'(scc Fig. 2,) and in case of the absence of filling willimovc back the tilling-fork slide 48 and through intermediate connections operate the shipper-lever 49 to stop the loom in the ordinary and well-known way.

5 I will now describe the filling-supply mech- (See Fig. 1,) A downanism shown in the drawings and embodying .my improvements and to which my improvements particularly relate. in this instance the magazine or reservoir for holding the bobbins is of the Northroiti type, above rcfer-red to, and is combined with the shifting shuttle-boxes at the opposite end of tne loom through intermediate connections to be oper ated to supply filling according to the movement of the shuttle-boxes.

The lower end of a connector 50, Fig. 1, is connected to the vertically-nioving box-rod 10, and its upper end is connected to one end of a lever 51, centrally pivoted at 51 The opposite end of theflever 51 has pivotally and' adjustably attached thereto the lower endbt' a connector The upper end of the conmeter- 52 is pivotally attached to a pin 53 on one arm oi the angle-lever 54. Said anglelever5a is pivotaily mounted on a stud 55, and the other arm of said. angle-lever 54 is .in this instance made forked or slotted at its end to receive-one end. of the connector 56. The other end of the connector 56 is adjustably and pivotally attached to onearm of an angle-lever 57, pivotally mounted on a stud ,58. The other arm of the angle-lever 57 is pivotally connected to the upper end of a link 59. (See Fig.- 3.) The lower endot' the link 59 is pivotally connected to an arm 60, which .in this instance extends through an opening 61' in the stand 61, which is secured .upon the breast-beam and by the bracket 62 to the loom-arch. The inner end of'the arm is fast on a rocking sleeve 62, loosely mounted on a pin (i3, secured to and extending out from the stand (31 and forming the pivotal support for the sleeve 62. (See Fig. 3.) Through the arm 60 and the intermediate coir nections to the vertically-moving box-rod 10 a rocking movement is communicated 'to the sleeve 62 in one direction or the other, according to the vertical movement of said rod 10 and the shifting shuttle-boxes connected therewith.

I will' now describe the magazine for the bobbins shown in the drawings and which in this instance embodies my in'iprovements.

East on thcinner end of the sleeve (52, in this instance secured thereon by a set-screw 64, is a hub 65' of a circular plate or disk 65. (See Fig. 3.) The periphery of the disk65 extends within an annular lip or flange 61 on the edge of the plate or stand- 61. (See Fig. 3.) Thedisk 65 has an annular lip or flange 65" thereon, which in connection with the flange 613 on the plate ()1 forms guideways 65' upon its outer surface near its circumference of curved shape, conforming tothe curved shape of the disk 65. (See Fig. 4.) The guideways 65', in this instance two in number and arranged upon the opposite sides of the axis or pivotal support of the disk 65, form compartments for the heads of the bobbins 9, which are placed therein from terror therewith in the ordinary Way, in this bin in one guideway at the lower end of the guideways to form a stop or terminal for the head of the lowest bobbin in each guideway. In this instance the stop or division 66 is a radial projection on the disk 65. The flangefil on the plate 61 is cutaway or has an opening therein to allow of the passing'out therefrom of the head of the lowest bobbin therein, as shown.

\Vhen the head of the lowest bobin Fig. 4.

rc tly unde the transferrer 67, as shown in Fig. 4, it will be yieldingly held in positionpreparatory to being discharged from the guideway by the engagement of the transinstance by a stationary plate 68, having grooves 68' on its upper side to position the head of the bobbin, and also by a spring-ac: tuated pawl or supporting-arm 69, which is pivotally mount-ed on a pin 70 and has an extension 69' thereon, with aspring' 71 attached thereto and to the plate 61. (Seeliig. l.) In connection with theplatti or disk 65 for the heads of the bobbins 9 a second plate or disk 72 may be used for the tips of the bobbins 9. The disk 72 has a hub 72 thereon, which is fast on the rocking sleeve 62, in this insta'ice secured thereon by a set-serew 73. The disk 72 has guidcways 72 upon its inncr side formed by two annular flanges 72" ofg'curved shape and corresponding to the curvature of the disk 72 and also to the curvature of the guideways 65'. The outer flange 72 has an opening therein at its upper part for the insertion of the tips of the bobbins into the guideways 72. (See 5.) The'ofiter flange 72 also has an opening therein at its lower part for the discharge of the tips of the bobbins. (See Fig. 5.) There are in this instance two spring-blades '74, secured at their upper ends to the lower part of the disk '32, with their lower free ends extending inwardly each one against and'slightly under a tip of the lowest bobbin 9 in each compartment, as shown in Fig. 3, toyieldingly hold said bobbins at their tip. ends.

The two sets of guideways 65', as shown in thedrawings, for the heads of the bobbinsf and 72 for the tips of the bobbins form, in

this instance, two separate compartments in a magazine of the Northrop type, above referred to, each compartment adapted to hold a series of bobbins, one series preferably being adifl'erent color from the other, which bobbins are inserted at the upper ends of the guideways and drop down by gravity to the bottom thereof, and a bobbin in its lowest position in one or the other is in a position diof the compartments when the loom is running is yieldingly held directly under the transferrer and ready to be transferred into the running-shuttle, on the substantial exhaustion of filling in the running shuttle.

The transferrer mechanism may be of the usual and well-known construction in the class of looms with which my improvements are intended to be used and consists in this instance of a transferrer-arm 75. secured upon a rockshatt 76 and extending through an opening 61" in the plate 61, having on its inner end the horizontal transferrer-arm 67, above referred to. (See Fig. 3.) The transferrerarm is'operated to transfer a fresh bobbin 9 into the running shuttle on the substantial exhaustion well-known offilling therein in any usual and way and in this instance by the I engagement of the bunter'72' on the lay with the finger 78, pivotally mounted on the ower end of an arm 78', fast on the rock-shaft 76, when said finger 78 is raised into the path of the hunter 77, in this instance by means of the mechanism shown in the drawings, and par ticularlyin Figs. 7, 8,and 9. The innerend" ot' the longitudinally-moving rod (see Fig, 9,) which is connected at its outer end with the detector-arm 30, as above described, is

supported and moves in a side boss orpro jection 81 on a vertically-moving" plate supported on the inner side of the beam. The vertically-moving plate 81 a verticaLopening 81 therein, (see Fig. 9,} into which extends the upper end p1 a vertiealt moving rod 82, which is pivotally attached at its lower end to onearm of an angle cam-lever 83, pivotally mounted on astud 84. The other arm of-the angle-lever 83 carries a roll 83', which travels in a cam-groove in a cam 85, fast on the bottom shaft 1%. (See Fig. 7,) fihlljough the rotation of the cam 85 an op ned-down motion at regular and predetermined intervals is communicated to the vertically-moving rod 82. A spring 86, attached to the lowerend of the frame 1 of the loom and its upper end toe projection onthe vertically-movingplate $2, acts to return said plate to its normal lowered position after it has been raised, The upper end of the plate 81 has a slot therein fl'into which extends a pin 79, fast on an arm '79 on the rock-shaft 76. Fast on the rock-shaft 76 is an arm 80, carrying at its lower end aliult 80, havingthe hooked end adapted to extend over a projection 7 8' X ing down from a finger 78, which ispivotally (mounted on the lower end of theatm Y8. A.

with the finger 78 coil-spring- 87 is connected and acts to move up said bo ler to tstopera tive position (sh own in" Fig; 8) w hen said as ger is released from engagement-with the link 80 on the downward movement of the arm 80- through the operation of the spring 88 when the upward m'wemcnt of theslidehl releasqe the arm\ 7 ).1 W hen the detector-arm 30 is rod 82. By reason of the end of the rod 33' l liv d moved back of one of the feeler being drawn out of its normal position by contact with the band on the bobbin, the -longitud'inallymoving rod 33 will be moved to the right in Fig. 2 and to the left in Fig. 9 to extend in the path of the upwardly-movin extending in thepath of the upper end of the rod .82 the upward movement of said rod through the rotation of the cam 85 and the movement of the cam-lever 83 will move upwardly the slide 81 against the action of the spring 86 and allow the spring 88- to act to lqyver the arm 80 and move inwardly the link 80 to release the projection 7 8 on the finger 78 and allow the spring 87 to operate to raise the linger 78, as shown in Fig. 8, into position to be engaged by the hunter 7'? (shown in Fig. 1) to cause the operation of the transferrer-arm to supply fresh filling, all as will be fully understood by those skilled in the art.

It will be understood that the details of construction of my improvements may be varied, if desired, and my improvements in the magazine. or reservoir may be adapted to be applied to and used on filling-change'mechanism looms of diflercnt type and with or vvithout the particular form of rotary magazine of the Northrop type shown in the draw ings herein.

The term compartment as herein used is intended to include. broadly, any means in the magazine to guide a group of superposed bobbins or filling-carriers in their movement to the discharging end of the magazine preparatory to the removal of the bobbins duri'ng the operation of the loom.

The term "bobbin as herein used is intended to include any form of fillingearrier suitable For use in a iilling-carricr magazine.
